Figure out release process so NPM package is synced with GH repo

[kaganjd]

On this branch, I'm importing the libs (p5, p5.serialport, p5.dom) as node modules. This way, we get the latest versions each time we npm install... but it will only work if the NPM modules are up to date.

Great! Want to make a pull request?

I'm wondering if I should figure out the release process first? Otherwise, if you merge this in and run npm install now as is, the p5.serialserver module it brings in from NPM is not the most up-to-date version (the most recent version is currently only on Github). What do you think about order of operations here?
